摘要：
The utility model relates to agricultural machinery, in particular, to seeders for sowing grain crops.Combined sowing unit includes a frame with a towing device, a hopper with sowing devices, support wheels, coulters. Each coulter contains a stand, paw and piping. The outlet of the piping is directed into the sublap space of the paw. On the back of the rack there is a bracket, a rod with a spring and a seed tube. A wedge-shaped tip is rigidly mounted from the lower part of the vas deferens and the tip is directed towards the opener movement, and the outlet openings of the vas deferens and pipelines are located at a distance equal to the required difference in the depth of seeding of fertilizers. Behind the coulters, a roller attachment is installed, containing successively mounted rollers of the loosening and leveling type, an H-shaped frame, brackets and rods. Nuts and a spring are installed on each rod. The cultivating roller contains an axle and disk cultivators. Disc rippers are mounted on the axis of the ripper type roller at equal intervals in the horizontal plane, and triangular recesses are made along the periphery of the disc rippers. The leveling roller contains an axle, side and intermediate disks, and rippers. The rippers are installed in such a way that they form a helix, the direction of which begins from its longitudinal axis of symmetry and is directed towards the side discs. The rippers in the cross section are square and twisted along the entire length by an angle α relative to their longitudinal axis of symmetry so that the sharp edges of each ripper form helical lines, and the sharp edges of the rippers are directed in different directions from the geometric axis of rotation of the leveling roller.Such a design of the combined sowing unit will improve the quality of sowing of grain crops.Полезная модель относится к сельскохозяйственному машиностроению, в частности, к сеялкам для посева зерновых культур.Комбинированный посевной агрегат включает ра
